One question about Postgres-XC, can it distribute one single query in all nodes ? Example, Nodes: Node1,Node2,Node3 Query:"SELECT sum(foo) FROM bar group by foo" (Obvious: Your data has to be shared between the nodes) Query -> Compiler (in the pool)-> "share the query between the nodes" -> merge

Version 1.1 will be out in this June time frame, with online node addition/removal, Trigger and improved planner. I'm more than happy if you evaluate XC. Regards; -- Koichi Suzuki 2013/3/4 Greg Jaskiewicz : > > On 4 Mar 2013, at 13:21, Vincent Veyron wrote: > >> >> There is this : >> >

2013-03-03 Thread Gregg Jaskiewicz
Hi guys, I'm looking into setting up an HA scalable DB cluster. So far my tests with streaming replication proof that it is very very good indeed. However, problem seems to be on the connection pooling side. Ideally, we would love to have single point of connection to the cluster, but I do realis
